A death investigation blocked most lanes on northbound Interstate 5 Thursday morning in North Seattle, halting rush-hour traffic.

The closure occurred near Northeast 85th Street. Crews opened the freeway to all lanes by 8:50 a.m. All lanes were blocked at one time, with lanes opening one at a time, according to the state Department of Transportation. WSDOT claimed the backup extended at least five miles to the convention center downtown at its peak.

A woman reportedly jumped from an overpass and was hit by a car on the freeway below, State Patrol spokesman Trooper Rick Johnson said. Authorities attempted CPR, but the woman died on site. Investigators are using a drone to map the scene and continue to look into what happened, causing the blockage.
